To all whom it may con/ eerie.-

Be it knownthet I, WiLLIAM C. Hermes DINGER, a resident of Louisville,in the county of Jefferson and State of Kentucky,

' -heve invented certain new and useful Imrovements in Safety-Razors andI dohere- Ey declare the following-to be at full, clear,

and exact description of the invention, such as will enable othersskilled in the art to c which it epperteins to make and use the some.

My invention relates to improvements in soi'etydazors, the object oi theinvention being to provide improved means for quickly, accurately, andsecurely locking the parts together with the blade or blades in place.

A. further object is to provide an improved blade for safetywezors.

Hcretoforc sslety-rezors have been uni- 2c formly secured in assembledformation by means of scrcvwtl'lreaded parts, which may be adjusted tootightly to the injury of the razor or may be left too loose and tail towork properly.

My improved connecting or locking mcch enisln lcsv'es nothing; to thejudgment of the user and 'elt sys insures it perfect assemblage of portsand is strong and lura'ible in use.

With these objects in View the invention consists in certain novelfeatures of construc tion. and combinations one arrangements of parts,as will he more lull lieroinefter do scribed, and pointed out in claims.

' The guard secured to the by means of screws 7, the latter screwed intothreaded openings in the slotted portion of the cross-head and servingas stops to limit the movement of the locking-slide 4. The upper ends ofthe screws above guard 5 are made with enlarged heads, which, togetherwith a central collar 8 on the go ird, serve to guide the blades 18 toproper position. This central collar registers with openings in theggxmrrl, cross-heud 3, end guide-block 2 to receive a centrel stud ,10on the curved backing l 1, the collar is preferably made with internalguide pins 01' lu s 1.2 to enter longitu- (linal grooves 13 in stu 10toinsure the back ing hein properly placed. also met e with a slot 14-to receive the lock lug-slide 4 when the letter is slid to lockingposition, as will now be explained.

'lhelocking-slide 4 comprises a metal plate and crosshend 3 end isnotched at its upper corners, providing shoulders 15 to strike screws 7and limit the movement of the slide. The olote also made with a. slot 16extend ing rem its upper edge downward to near its lower end thenextending longitudinally of, the plate, providing a lockin 'tongue 5.7to enter the slot 14 in stud 10. T e lower edge of this tongue l7 ismade on an incline to exert cum action on the stud 10 to draw thehacking to its proper place to firml clamp the blades 18 in position.When the slide is moved to one extreme position, the slot ill willpermit the stud 10 to be readily removed or inserted, and when. theslide is moved to its other extreme position the Each blade comprises a,strip of cross-head 3 The stud 10 is tongue 1ft" will be in the is ofstud 10,

mounted to slide in the slot in guide-block 2 thin steel having a sharplongitudinal cutting edge, the opposite longitudinal edge being providedwith three notches 19 to receive the screws 7 and collar 8, and theblade is notched at its ends to fit between the up turned ends 6 ofthc'guard and provide lugs 20 to roject out through the notches 6. Theseugs afford an easy and safe finger-hold to handle the blade, and they,together with the notches 19 against the screws 7 and collar 8, insurethe blades being properly placed on the guard, as it is quite impossibleto place the blades in any other position.

When the blades are in position, the backing-stud 10 is inserted throughcollar 8into guide-block 2, and the locking-slide is movedlongitudinally to lock the arts, as above explained, and the blades willbe tilted by the edge of the curved backing so as to lie fiat againstthe guard-fingers in correct position for shaving with perfect ssfiety.A great many slight changes might be made in the general form andarrangement of the parts described without departing from my invention,and hence Ldo not re strict myself to the precise details set forth,

but consider myself at liberty to make such slight changes andalterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim asnew, and desire tosecure by Letters Patent, is-

1. In a razor, the combination with a uard and a backing, oi a stud onthe backing to enter an opening in the guard said stud having a slottherein, and a locking; device constructed to pass through said slot andlock the parts together.

2. In a razor, the combination. with a guard and a backing, of a studonthe backmg to enter an opening in the guard said stud having atransverse slot between its ends,

and a sliding locking plate or bar constructed to pass through thetransverse slot in the stud and lock the parts together. 3. In a razor,the combination with a handie having a slot therein, a guard securedthereon, a backin and a slotted-stud on the backing to enter the handle,of a sliding locking-plate in'the slotted handle and a tongue on thelocking-plate to enter the slotted stud and lock the parts together. a

e, In a razor, the combination with a slotted guide-block, and a guard.securedv thereon and having opening alining with an opening in theguide-block, of a backing,
